The main advantages of pneumatic flange butterfly valve are simple structure, small size, light weight, low cost. The pneumatic disc valve is especially prominent. It is installed in high-altitude dark channel. It is easy to control and operate through two-position five-way solenoid valve, and it can also adjust the flow medium. Fluid resistance is small, the effective flow area of medium and large caliber pneumatic disc valve is large when it is fully open, and the opening and closing is quick and labor-saving. The disc can be opened and closed by turning 90 angles. Because the medium force acting on the disc plate on both sides of the rotating shaft is close to the same, the direction of the torque produced is opposite, the opening and closing moment is small, and good sealing can be achieved under low pressure. The sealing materials of disc valves are NBR, fluorine rubber, edible rubber and tetrafluoroethylene lining, so the sealing performance is good. Hard sealing disc valves are hard and soft laminated metal sheets, which have the advantages of metal hard sealing and elastic sealing, and have excellent sealing performance at low temperature.
